The special metal bond structure of iron cobalt nickel leads to their paramagnetism?
Yes, metals such as iron cobalt nickel have special electronic structures that allow them to be strongly magnetic. In these metals, each atom has unpaired electrons in its outer shell that can interact to create magnetism. Such magnetism is called paramagnetism because they align along the direction of the magnetic field. Because of this special electronic structure, metals such as iron-cobalt-nickel can be used to make magnetic materials and magnetic memory devices.
The special metal bond structure of iron cobalt nickel leads to their paramagnetism
The nature of a magnet attracting iron, cobalt, nickel and other substances is called magnetism. The area with strong magnetism at both ends of the magnet is called a magnetic pole, one end is the north pole (N pole), and the other end is the south pole (S pole). The opposite magnetic poles attract each other. There are many original magnets with two opposite magnetic poles in iron, cobalt, and nickel. When there is no external magnetic field, these original magnets are arranged in disorder, and their magnetism cancels each other, and they do not show magnetism to the outside.
When the iron When approaching the magnet, these original magnets are neatly arranged under the action of the magnet, so that the end close to the magnet has a polarity opposite to that of the magnet and attracts each other. This shows that the iron can be magnetized by the magnet due to the existence of the original magnet .Metals such as copper and aluminum do not have the original magnet structure, so they cannot be attracted by magnets.
How many kinds of magnetism are there in the world? The different characteristics of magnetism, weak magnetism is divided into diamagnetism, paramagnetism and antiferromagnetism, and strong magnetism is divided into ferromagnetism and ferrimagnetism. These are the magnetism generated by electrons in the atoms of macroscopic substances, and the nuclei in atoms It also has magnetism, which is called nuclear magnetism. But nuclear magnetism is only about one-thousandth or lower than that of electron magnetism. Therefore, in general, both material magnetism and atomic magnetism mainly consider the electron magnetism in atoms. The low magnetism of the nucleus is due to the nuclear The quality of electrons is much higher than that of electrons, and nuclear magnetism still has important applications under certain conditions. Abbreviation), is the application of the magnetism of hydrogen nuclei. Magnetic materials can be divided into soft magnetic materials such as iron and hard magnetic materials such as steel. And applications. From our body and surrounding substances, to various stars and interstellar substances, atoms, nuclei and elementary particles in the microcosm, and various materials in the macrocosm, all have magnetic properties in one way or another.
